Electra was daughter of Agamemnon and Clytemnestra in Greek mythology. She and her brother Orestes take vengeance on their mother Clytemnestra and step father Aegisthus for the murder of their father, Agamemnon, following the Trojan War.

There are two classic Greek plays about Electra, one by Sophocles and one by Euripedes. It is not clear which of these was produced first, although it is believed both were written in the early 400s BC.
